Subject: [PATCH] meta_screen_foreach_window(): Skip override-redirect windows

Don't include override-redirect windows when iterating the windows
in the screen. We don't need them for any of the current uses:

 - Queueing redraws and resizes on managed windows
 - Checking which windows should be added to a new workspace
